I think it's totally irresponsible on the breeders part to not have recognised the mite issue prior to shipping them to a customer. Sure, things happen but it's really negligent as well. Any animal that is up for sale consideration should be scrutinized for health and wellness prior. The onus is directly on the breeder and he actually shouldn't expect you to accept the shipment. He should've faxed over a return shipping label with his sincerest apologies. He should also immediately return your money and let you know that it's unacceptable for you to have to treat these snakes. They are still his responsibility for at least 24 to 48 hrs on any reputable breeders health certificate or statement. He needs to make it crystal clear that he will be assuming the responsibility for selling a customer diseased animals.
